Answer:
After 4 movies it will be equal
Step-by-step explanation:
10x + 160 = 50x
160 = 40x
4 = x
Check:
10x + 160 =
10(4) + 160 =
40 + 160 = 200
50x =
50 x 4 = 200
200 = 200
Answer:
6x^2 + -10
Step-by-step explanation:
Hi there! I'm glad I was able to help you answer this polynomial expression!
All we're really doing to solve is combine like terms.
(5x^2+2) - (-4x^2+7) + (-3x^2-5) = _____________
5x^2 + 2 + 4x^2 + -7 + -3x^2 + -5
(5x^2 + 4x^2 + -3x^2) + (2 + -7 + -5)
6x^2 + -10
The terms that have x^2 at the end are in bold letters so you know what we're combining them - the other numbers are the separate like terms.
Simplified, our answer is 6x^2 + -10.

Solve for x then replace x with f⁻¹(x) and y with x
y=(4^x-5)/3
times 3
3y=(4^x-5)
add 5
3y+5=4^x
take log₄ both sides
log₄(3y+5)=x
switch
f⁻¹(x)=log₄(3y+5)
